Struct kaige::TryWrite

pub struct TryWrite<T>(/* private fields */);

Writes a single entity data component type from a chunk.

Trait Implementations

impl<T> Clone for TryWrite<T>

where T: Clone,

fn clone(&self) -> TryWrite<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> Debug for TryWrite<T>

where T: Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<T> Default for TryWrite<T>

fn default() -> TryWrite<T>

Returns the “default value” for a type.

impl<T> DefaultFilter for TryWrite<T>

where T: Component,

type Filter = EntityFilterTuple<TryComponentFilter<T>, Passthrough>

The filter constructed.

impl<'data, T> View<'data> for TryWrite<T>

where T: Component,

type Element = <<TryWrite<T> as View<'data>>::Fetch as IntoIndexableIter>::Item

The type of component references returned.

type Fetch = Slice<'data, T>

The fetch type yielded for each archetype.

type Iter = TryWriteIter<'data, T>

The iterator type which pulls entity data out of a world.

type Read = [ComponentTypeId; 1]

Contains the type IDs read by the view.

type Write = [ComponentTypeId; 1]

Contains the type IDs written by the view.

fn validate()

Determines if this view type is valid. Panics if checks fail.

fn validate_access(access: &ComponentAccess<'_>) -> bool

Returns true if the given component access includes all permissions required by the view.

fn reads_types() -> <TryWrite<T> as View<'data>>::Read

Returns the component types read by the view.

fn writes_types() -> <TryWrite<T> as View<'data>>::Write

Returns the component types written to by the view.

fn reads<D>() -> bool

where D: Component,

Returns true if the view reads the specified data type.

fn writes<D>() -> bool

where D: Component,

Returns true if the view writes to the specified data type.

fn requires_permissions() -> Permissions<ComponentTypeId>

Returns a permissions struct declaring the component accesses required by the view.

unsafe fn fetch( components: &'data Components, archetypes: &'data [Archetype], query: QueryResult<'data> ) -> <TryWrite<T> as View<'data>>::Iter

Creates an iterator which will yield slices of entity data for each archetype.

impl<T> Copy for TryWrite<T>

where T: Copy,

impl<T> Send for TryWrite<T>

where T: Send,

impl<T> Sync for TryWrite<T>
